Effect.Since the manufacture craft of lightning protection cold draw net is to be sent into the expanded net machine guide table of metallic coil band to watch with numerical control
Between taking the loading and unloading roller of feeding circuit, under the control of accurate digital control servo motor above and below the feeding of uniformly continuous in cutting die,
So reduce because mechanical feed precision is not high, feeding unevenness generate travers the defects of, with 800 times per minute speed handles
Metal sheet band shear tension is at the metal mesh with diamond-shaped meshes, and upper cutting die fixes diamond-shaped meshes long-pitch (1-10M M), by machine
The numerical control vertical lift system control mesh short pitch (0.5-5MM) of device has metal tape shear tension at the requirement for meeting parameter
There is the metal mesh of diamond hole.It extends net machine and uses advanced design concept, using elaborate servo digital control system pushing precision error
Less than 0.005MM, because feeding is uniform, the small travers for eliminating product of error ensure that the surface density of product well.For
Ensure the metal mesh that sizing grid is consistent, eliminates wide screen face out-of-flatness, can produce the very high wide size of mesh precision, mesh precision
Error is less than 0.01MM, and surface density error is can be controlled within 5G/M2, to improve the overall leveling of wide screen, is set in upper lower slide
Cutting die micro-adjusting mechanism is counted, control accuracy can be accurate to 0.001MM.To ensure that the winding without damage of forming mesh uses electricity
Son induction tension system, automatically controls in winding pulling force wrapup procedure and keeps mesh indeformable, foldover, net volume be not neat for wire side.
Stretch in correction due to metal material and stretch mesh technique unavoidably make made of metal mesh generate non-uniform stress, from
And metal mesh is caused to have the defects of bending, surface irregularity, bent wooden dipper, it is necessary to use and stretch correcting process together.It is put using second
Volume machine loads onto the diamond hole metal mesh of extension forming (with tension deviation-rectifying system), and adjusting tension (15-25KG ranges) will
Metal extends net and is aligned on four rollers of levelling machine at the four-roller DC speed regulation specially designed that is wound in of S shapes, four-roller design point
It not being driven by four direct current generators, the characteristic that can stablize stepless speed regulation using direct current generator is equipped with special velocity feedback circuits,
The speed for accurately controlling each roller, the tensile stress generated using the speed difference between four rollers stretch smoothing metal reel wire, warp
Crossing this procedure can allow the side crooked radian of net to be less than 1M M/6M, and surface irregularity degree is less than 2MM/6M, and eliminates wooden dipper song and lack
It falls into, it is coiled to receive net using 1300B type winders.Slitting trimming process, this procedure are to ensure more accurate product width, disappearing
Except selvage bending has better straightness.It will be wrapped on 1300 unreeling machines by the metal mesh for stretching correction, by unreeling machine
Pressure sensitive roller, buffer roll, transition roller unreel, reuse by improving dedicated metal mesh banding machine by banding machine guiding
Device, cutting cutter shaft, by width requirement parameter slitting trimming, the net width trueness error after cutting is less than 0.05MM, further school
The both sides straightness of positive wire side, then this road is just completed by the collecting shaft winding on cutting machine and cuts network process.Leveling calibration net is thick
It is the thickness met the requirements that technique, which is then the metal mesh after cutting, further increases flatness, the appearance quality of wire side,
Design need to pass through the thick technique of leveling calibration net together, be operated using to roll squeezer, straightening machine and mating retractable volume equipment.Through
The metal mesh crossed after cutting loads onto the unreeling machine rectified a deviation with tension, enters two pairs of rollers by pressure sensitive roller, buffer roll, transition roller
Machine passes through servo motor adjustment up-down rollers gap, after ensureing that the thickness of net reaches requirement thickness using the pressure between two rollers, fortune
Row equipment.Netcom's overcorrection machine by flattening is carried out last wire side smoothing, is extended by this rolling and metal after smoothing
Thickness of net error precision is certifiable less than 0.01MM and more smooth.Finally use with tension rectify a deviation 1300 type winder into
It is coiled that row receives net, on Scroll with brown paper and polychlorostyrene alkene film carry out it is preliminary pack, unload reel wire and complete production most
Technique afterwards.Therefore, the above-mentioned cold draw net for anti-lightning strike electromagnetic shielding, (as needed using bulk metal thin-band material
Can be copper, nickel, aluminium etc.) forming of extending, smooth (wire side thickness is accurate to 0.01MM) the grid longitude and latitude node of wire side is non-overlapping, whole
A wire side silk stalk size accuracy can be controlled in 0.01MM, and the surface density error of net can control within 5g/m2, and percent opening maximum can
Reach 80%, can arbitrarily adjust, can answer extensively in series of parameters such as mesh, silk stalk, thickness, surface densities according to actual needs
For anti-lightning strike and electromagnetic shielding field.Realize that improve precision, flatness, the mesh uniformity and size and weight consistent
Effect.
